Hi, I'm 38 years old, and fell off of my bicycle this morning while out exercising. My left knee got scraped up really good, and I think I caught myself with my left hand, because my wrist was hurting for a while afterwards. Now that I've taken a bunch of Ibuprofren, the pain in my wrist is better, but I can't bend my elbow more that about 20 or 30 degrees, and it hurts like mad if I try to force it. What can I do?
